Smith and Leto were joined by co-stars Margot Robbie and Cara Delevingne in front of a crowd of screaming fans to introduce a new trailer for David Ayer's highly anticipated supervillian film.

The cast of David Ayer's Suicide Squad assembled at the MTV Movie Awards to tease a sneak peek of the upcoming supervillian film.

Will Smith, the recipient of the night's Generation Award, walked out of a graffiti-covered jail cell and was joined by co-stars Margot Robbie, Cara Delevingne and Jared Leto as the foursome gathered in front of a crowd of screaming fans to introduce a new trailer for the highly anticipated film, set to hit theaters Aug. 5.

Leto offered a dirty intro, teasing that the film has "blood, sweat, semen, pubic hair, brains and anal beads" and that he "can't wait to share it with you crazy motherf—ers."

Smith then asked fans, "Are you ready for the worst heroes ever?" before MTV aired a shortened version of the new trailer.

The trailer features Viola Davis' character talking about wanting to assemble a team of criminals, with the recruits, including Harley Quinn (Robbie), checking out the weapons and battle gear they've received. During one scene, the villains are instructed not to disobey, escape or "irritate or vex" their leader, played by Joel Kinnaman, with Quinn raising her hand and saying she's "known to be quite vexing, I'm just forewarning you."

The rest of the trailer shows the Suicide Squad in action.

Suicide Squad stars Robbie as Quinn, Delevingne as Enchantress, Smith as Deadshot, Kinnaman as Rick Flag, Adewale Akinnuoye-Agbaje as Killer Croc, Karen Fukuhara as Katana and Leto as the Joker.
